Bypass support was added in commit d38018f2019c ("regulator: anatop: Add bypass support to digital LDOs"). A check for valid voltage selectors was added in commit da0607c8df5c ("regulator: anatop: Fail on invalid voltage selector") but it also discards all regulators that are in bypass mode.

2014-11-26regulator: of: Add regulator desc param to of_get_regulator_init_data()Javier Martinez Canillas1-2/+3
The of_get_regulator_init_data() function is used to extract the regulator init_data but information on how to extract certain data is defined in the static regulator descriptor (e.g: how to map the hardware operating modes). Add a const struct regulator_desc * parameter to the function signature so the parsing logic could use the information in the struct regulator_desc. of_get_regulator_init_data() relies on of_get_regulation_constraints() to actually extract the init_data so it has to pass the struct regulator_desc but that is modified on a later patch.

2014-03-18regulator: anatop: Remove checking control_reg in [set|get]_voltage_selAxel Lin1-23/+2
Remove checking control_reg in [set|get]_voltage_sel and then convert to use regulator_[set|get]_voltage_sel_regmap for [set|get]_voltage_sel callbacks. The anatop-reg-offset property is a required property rather than optional property. So the question is what is the meaning of setting anatop-reg-offset to 0? If 0 is a valid setting for anatop-reg-offset and it has special meaning, we had better document it in the binding document. Otherwise, remove the testing for control_reg in the driver. No anatop voltage regulator node in the dts files set anatop-reg-offset to 0. So I think it's safe to remove testing if control_reg is 0.

The ARM, PU, and SOC LDOs in the i.MX6 PMU can operate in bypass mode. This allows to use external switching regulators for cpu voltage scaling. Since bypass and power gating modes are not configured with their own bits, but via the voltage target bitfield, store bypass state to be restored when reenabling the regulator.

2013-02-08regulator: anatop: improve precision of delay timeShawn Guo1-2/+2
For cpufreq example, it takes 13 steps (25 mV for one step) to increase vddcore from 0.95 V to 1.275 V, and the time of 64 clock cycles at 24 MHz for one step is ~2.67 uS, so the total delay time would be ~34.71 uS. But the current calculation in the driver gives 39 uS. Change the formula to have the addition of 1 be the last step, so that we can get a more precise delay time. For example above, the new formula will give 35 uS. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
